., FigurrellO-isa'cletailsectien:talil A rically through the gears from the same view point as that of Figure 8; and l Figure 11 is a detail vertical section as seen from the side.

lReference to these views will now beV made by use of like characters which are employed to designate corresponding parts throughout. Y

Vith reference more particularly to Figure l` the frame of the machine is indicated by the numeral 1 and supports a motor 2 on a vertical axis. The frame also supports a gear box 3 having interior mechanism connected by a shaft 4 to the motor shaft 5 by means of a flexible coupling 6.

At each side ofthe gear box 3 is slidably mounted one of a pair of brackets 7 each having ay knuckle 8 at its upper end. Between the two knuckles is pivoted a curvedv upper track 9 having its ends formed with graduated discs 10 cooperating with index points 11 inscribed on the knuckles 8 as shown more clearly in Figure 4. By this means the upper track may be adj usted angularly and thenV secured in position by bolt and nut devices 12 passing through the discs and knuckles.

A pair of alined bearing members 13 and 14 (Figure 1) support a vertical spindle 15 to which is pivoted a link 16. This link is formed at one end with clips 17 supporting a vertical spindle 18 having at its upper end a bracket19 in which a jack base 2O is horizontally pivoted. The ack comprises a head 21 having a pair of racks 22 slidable and adjustable onopposite sides of the base 20 and having pivoted between them the upper jaw 23 of a heel blank clamp.

struction of the base 20 and adjustable racks 22 is more fully described and claimed in my co-pending application Serial No. 158,100,

Vtiled Dec. 30, 1926. The base 20 carries an Y naled on the frame and meshes with a pinion 28, Fig. 7, which is also rotatably supported by the frame. The pinion meshes with a rack 29 carried by the bracket 7, whereby the two brackets and consequently the elevation of the pivot supports of thel upper track 9 may be regulated. i

It will beseen in Figures 8 to 11 that the power shaft 4 from the motor extends into the gear box 3 and has mounted parallel to it an adjacent intermediate shaft 30 also journaled inside the box. The shafts 4 and 30 support narrow meshed cast iron gears 31 and 32 respectively.A The gear 31 has an upward sleeve extension 32 which is surrounded byV a smaller gear 33 of condensite celoron secured to the gear 31 by pins 34. The shaft 30 is {itted witha collar 35 having a'iiange 36 lying upon the gear V'32. Over this collar and in K The head 21 carries a pressure device 24 for the upper jaw v23, and this mechanism as well as the conport the drive gears 33y and 37.

engagement with the flange is mounted another condensite celoron gear 37 of the same size as the gear 33 and spaced slightly therefrom as shown in Figure 10. Pins'38 are passed through `the gear l37, flange 36 and `gear 32 so that all these parts turn with the shaft 30.

The gear box 3 is so arranged that the shafts 4 and 30 lie at equal distances from the ends of the track 9 and somewhat behind the track. Inwardly of the ends of the track, the gear box supports a pair of substantially tubular housings 40` eachV of which contains a vertical cutter shaft 41 mounted in ball bearings 42 at its ends as shown in Figure 11. This figure also illustrates conventional lroller bearings 43 for the upper ends of the shafts 4and 30. The shaft 4, as shown in Figure 9, is received in ball bearings 44 1n the bottom of the box 3. vAn annular space 45 is provided around the shaft and contains a ring 46 screwed on the shaft for supporting the inner ball race 47. The race is held against upward movement by a colla-r 48 on the shaft,

while the outer race 49 is fitted in a notch 50 'cut in the wall of the opening 45. and is held down by the usual plate 51.

To the bottom of the box is applied a plug 52 having a short ring 53 which threads into theV wall of the space 45. The inner circumference of the plug has awall 54 of about half inch in thick- Y ness built thereon and received between the Y shafts and the ring 46. A narrow space 55 is maintained between the bottom of the box 3 and the gear 31 and leads to the space 45. This construction provides an effective lubricating system which admits oil through the space 55, retains thel oil inthe space 45 and prevents it from flowing down the shaft 4 by means of the inner collar 54. Y

The lower ends of the two shafts 41 lie adjacent the condensite celoron gears 33 and 37 and are fitted with pinions 56 meshing. with these gears.` Condensite celoron is used for the gears 33 and'37A in order to eliminate the noise which would result from the high speed imparted to the pinions 56. The lower gears 31, and 32 serve merely to transmit motion from the shaft 4 to the shaft 30-and to sup- The upper ends of the cutter shafts 41 are exposed outside their housings `40 and there i equipped with the cutter blades 57 which are clamped down .bynuts 58 screwed on the shafts The upper extremities of the shafts project beyond the nuts and are squared as indicated by the numeral 59 in Figures 1 and 4.

LAdj acent each cutter, the top of the frame is formed with a rest 60 having sockets 61, Fig. 11, in diagonally opposite corners thereof. A duct 62 is formed inthe rest and in the frame to lead from the socket to the upper ball bearings 42 of the nearer shaft 41. rsystem ofl ducts may further be providedA to i "lead fromtthelsame socket-61 tothebearings of the other shaft 4l so that'pil may befed ,to these hearings fromfasingle"point.
